泡沫型干扰幕及其多波段干扰特性研究

现有多波段干扰技术普遍存在作用时间太短、于扰波段不够宽等问题，为此研究了新型 的泡沫型干扰幕技术。介绍了它的多波段干扰原理、原料配方和特定的反应过程，研制了专用的施 装置并给出了它的设计要領。对红外成像系统、毫米波雷达、厘米波雷达和可见光的干扰实验结 果表明：当它的气泡平均直径约为0.5 mm时，其高效干扰层厚度只是厘米量级，高效千扰时间则 在0.5h以上，并且它使用后留下的残留物对环境无污染。

Study on Special Foam Screen and Its Multi-band Interfering Performance

In order to overcome the shortcomings of the existing multi-band interfering techniques, a new interfering technique using special foam screen was put forward. Its interfering mechanism, the selected chemicals and the process of reaction were studied, and a foam screen set with an ejector was developed. The test results show that when the diameter of air bladder is about 0.5 mm, the special foam screen with 2?4 cm in thickness can interfere IR, MMW, CMW and visible light, and its inter?fering time can last for more than 0.5 h. The remains of this foam screen has no pollution to environ?ment.
